Natural fiber reinforced composites are gaining attention nowadays due to their low cost, biodegradable characteristics, lower density and comparable mechanical properties with synthetic fibers reinforced composites. As the recyclable properties of these composites are still not fully explored and this could be the reason that these are not much used in domestic and other applications to their full potential. In the current experimental investigation, the effects of mechanical recycling on the properties of bagasse fiber reinforced polypropylene composites have been studied. Tensile properties, crystallinity and aspect ratio exhibits an increase, while flexural properties decrease with each recycling step. No significant change in thermal behavior has been detected even after 5 cycles but a slight increase in the hardness has been observed. SEM images confirmed the change in aspect ratio due to crushing of fibers as well as fiber fracture became more dominant after each recycling step.

如今，天然纤维增强复合材料因其低成本，可生物降解的特性，较低的密度以及与合成纤维增强复合材料相当的机械性能而受到关注。由于这些复合材料的可回收特性仍未得到充分研究，这可能是其在家用和其他应用中未能充分发挥其全部潜力的原因。在当前的实验研究中，已经研究了机械回收对甘蔗渣纤维增强聚丙烯复合材料性能的影响。拉伸性能，结晶度和长宽比显示出增加，而挠曲性能随着每个再循环步骤而降低。即使经过5个循环，也未检测到热行为的显着变化，但观察到硬度略有增加。
